According to Kirby, the U.S. is talking to the Ukrainians "in real time."
"We want to better understand what is going on here. In the meantime, we will continue to make sure that Ukraine has the weapons and capabilities it needs to defend itself," he said, adding that new military aid packages will be announced in coming weeks.
Earlier reports said that the Ukrainian Armed Forces had taken control of more than 1,000 square kilometers of territory in the Kursk region with dozens of settlements.
